At least one Ukrainian missile struck the headquarters of Russia’s Black Sea navy in the Crimean port of Sevastopol on Friday, causing a fire, local governor Mikhail Razvozhayev wrote on Telegram.
Razvozhayev said another strike was possible and urged people to avoid the city centre where the building is located. Firefighters were at the site, he said.
Some Sevastopol residents said they heard explosions in the skies and saw smoke, Russian news outlets reported. Ukraine did not immediately claim responsibility for the attack.
One military serviceman was killed in a Ukrainian missile attack. The ministry said in a statement air defences had downed five missiles aimed at Sevastopol. These claims are yet to be independently verified.
Crimea, which Russia seized and annexed from Ukraine in 2014, has been a frequent target of Ukrainian attacks in the course of the 19-month war.
